Their signature Medallion fund is famed for the best record in investing history. Renaissance was founded in 1982 by James Simons ,
224-414: A bull market , distressed investing works best during a bear market . Risk arbitrage or merger arbitrage includes such events as mergers , acquisitions, liquidations, and hostile takeovers . Risk arbitrage typically involves buying and selling the stocks of two or more merging companies to take advantage of market discrepancies between acquisition price and stock price. The risk element arises from

It can provide custodial services for the fund's assets, and trade execution and clearing services for the hedge fund manager. Hedge fund administrators are typically responsible for valuation services, and often operations , and accounting . Calculation of
448-1006: A lack of transparency . Another common perception of hedge funds is that their managers are not subject to as much regulatory oversight and/or registration requirements as other financial investment managers, and more prone to manager-specific idiosyncratic risks such as style drifts, faulty operations, or fraud. New regulations introduced in the US and the EU as of 2010 required hedge fund managers to report more information, leading to greater transparency. In addition, investors, particularly institutional investors, are encouraging further developments in hedge fund risk management, both through internal practices and external regulatory requirements. The increasing influence of institutional investors has led to greater transparency: hedge funds increasingly provide information to investors including valuation methodology, positions, and leverage exposure. Hedge funds share many of

In 1988, the firm established its most profitable portfolio , the Medallion Fund, which used an improved and expanded form of Leonard Baum 's mathematical models , improved by algebraist James Ax , to explore correlations from which it could profit. Elwyn Berlekamp was instrumental in evolving trading to shorter-dated, pure systems driven decision-making. The hedge fund
672-535: A "fundamental growth" strategy invest in companies with more earnings growth than the overall stock market or relevant sector, while funds using a " fundamental value " strategy invest in undervalued companies. Funds that use quantitative and financial signal processing techniques for equity trading are described as using a "quantitative directional" strategy. Funds using a " short bias " strategy take advantage of declining equity prices using short positions. Event-driven strategies concern situations in which
784-440: A CTA from a regulatory perspective and the main divide is between systematic and discretionary strategies. A classification framework for CTA/Macro Strategies can be found in the reference. Directional investment strategies use market movements, trends, or inconsistencies when picking stocks across a variety of markets. Computer models can be used, or fund managers will identify and select investments. These types of strategies have
896-431: A computerized system, known as "systematic/quantitative". The amount of diversification within the fund can vary; funds may be multi-strategy, multi-fund, multi-market, multi-manager, or a combination. Sometimes hedge fund strategies are described as " absolute return " and are classified as either " market neutral " or "directional". Market neutral funds have less correlation to overall market performance by "neutralizing"

According to the Dictionary of Occupational Titles occupations in mathematics include
1232-521: A fund has too much exposure to a particular investment, sector, trading strategy, or group of correlated funds. These risks may be managed through defined controls over conflict of interest , restrictions on allocation of funds, and set exposure limits for strategies. Many investment funds use leverage , the practice of borrowing money, trading on margin , or using derivatives to obtain market exposure in excess of that provided by investors' capital. Although leverage can increase potential returns,

#17328012508811344-446: A fund manager "drifting" away from an area of specific expertise, manager risk factors include valuation risk , capacity risk, concentration risk , and leverage risk . Valuation risk refers to the concern that the net asset value (NAV) of investments may be inaccurate; capacity risk can arise from placing too much money into one particular strategy, which may lead to fund performance deterioration; and concentration risk may arise if
1456-470: A good year. Earnings at the very top are higher than in any other sector of the financial industry, and collectively the top 25 hedge fund managers regularly earn more than all 500 of the chief executives in the S&;P 500 . Most hedge fund managers are remunerated much less, however, and if performance fees are not earned then small managers at least are unlikely to be paid significant amounts. In 2011,
1568-403: A greater appetite for risk , with the intention of maximizing returns, subject to the risk tolerance of investors and the fund manager. Managers will have an additional incentive to increase risk oversight when their own capital is invested in the fund. Hedge fund management firms typically charge their funds both a management fee and a performance fee . Management fees are calculated as
1680-604: A greater exposure to the fluctuations of the overall market than do market neutral strategies. Directional hedge fund strategies include US and international long/short equity hedge funds, where long equity positions are hedged with short sales of equities or equity index options . Within directional strategies, there are a number of sub-strategies. " Emerging markets " funds focus on emerging markets such as China and India, whereas "sector funds" specialize in specific areas including technology, healthcare, biotechnology, pharmaceuticals, energy, and basic materials. Funds using
1792-439: A large amount of flexibility (due to their ability to use leverage to take large positions in diverse investments in multiple markets), the timing of the implementation of the strategies is important in order to generate attractive, risk-adjusted returns. Global macro is often categorized as a directional investment strategy. Global macro strategies can be divided into discretionary and systematic approaches. Discretionary trading
1904-550: A loss: 1989. During 2020 the Medallion fund surged 76%. "[Renaissance] won the [Labor Department]'s permission to put pieces of Medallion inside Roth IRAs. That means no taxes – ever – on the future earnings of a fund that averaged a 71.8 percent annual return, before fees, from 1994 through mid-2014." Renaissance Technologies terminated its 401(k) retirement plan in 2010 and employees' account balances were put into Individual Retirement Accounts . Contributions could be made to
2016-445: A management fee of 2% on total assets and a 20% fee on realized gains. In the 1970s, hedge funds specialized in a single strategy with most fund managers following the long/short equity model. Many hedge funds closed during the recession of 1969–1970 and the 1973–1974 stock market crash due to heavy losses. They received renewed attention in the late 1980s. During the 1990s, the number of hedge funds increased significantly with
2128-400: A manager is only rewarded if the fund generates returns in excess of the returns that the investor would have received if they had invested their money elsewhere. Some hedge funds charge a redemption fee (or withdrawal fee) for early withdrawals during a specified period of time (typically a year), or when withdrawals exceed a predetermined percentage of the original investment. The purpose of
2240-422: A manager will sometimes close a fund that has suffered serious losses and start a new fund, rather than attempt to recover the losses over a number of years without a performance fee. Some performance fees include a " hurdle ", so that a fee is only paid on the fund's performance in excess of a benchmark rate ( e.g. , LIBOR ) or a fixed percentage. The hurdle is usually tied to a benchmark rate such as Libor or

In 2005, Renaissance Institutional Equities Fund (RIEF) was created. RIEF has historically trailed the firm's better-known Medallion fund, a separate fund that only contains the personal money of the firm's executives. In April 2020, Institutional Investor reported that the disparity between Renaissance's Medallion fund and other funds, including RIEF,

They are usually expressed as an annual percentage, but calculated and paid monthly or quarterly. Management fees for hedge funds are designed to cover the operating costs of the manager, whereas the performance fee provides the manager's profits. However, due to economies of scale

Science and mathematics in the Islamic world during the Middle Ages followed various models and modes of funding varied based primarily on scholars. It was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. Funding for translation of scientific texts in other languages
2912-665: A position based on the predicted movement of the security or securities in question. Large institutional investors such as hedge funds are more likely to pursue event-driven investing strategies than traditional equity investors because they have the expertise and resources to analyze corporate transactional events for investment opportunities. Corporate transactional events generally fit into three categories: distressed securities , risk arbitrage , and special situations . Distressed securities include such events as restructurings, recapitalizations , and bankruptcies . A distressed securities investment strategy involves investing in
3024-410: A single strategy or multiple strategies for flexibility, risk management , or diversification. The hedge fund's prospectus , also known as an offering memorandum , offers potential investors information about key aspects of the fund, including the fund's investment strategy, investment type, and leverage limit. The elements contributing to a hedge fund strategy include the hedge fund's approach to

By 2012, Renaissance was granted a special exemption by the United States Labor Department allowing employees to invest their retirement money in Medallion arguing that Medallion had consistently outperformed their old 401(k) plan. In 2013, Renaissance's IRA plans had 259 participants whose $ 86.6 million contribution grew to $ 153 million that year without fees or annual taxes. Renaissance set up
3248-627: A state of maturity that is consolidating around the larger, more established firms such as Citadel, Elliot, Millennium, Bridgewater, and others. The rate of new fund start ups is now outpaced by fund closings. In July 2017, hedge funds recorded their eighth consecutive monthly gain in returns with assets under management rising to a record $ 3.1 trillion. Hedge fund strategies are generally classified among four major categories: global macro , directional, event-driven , and relative value ( arbitrage ). Strategies within these categories each entail characteristic risk and return profiles. A fund may employ
3360-401: A strategy based on predicting the final approval of new pharmaceutical drugs ; and legal catalyst strategy, which specializes in companies involved in major lawsuits. Relative value arbitrage strategies take advantage of relative discrepancies in price between securities. The price discrepancy can occur due to mispricing of securities compared to related securities, the underlying security or
3472-496: A substantial portion of the asset management industry, with assets totaling around $ 3.8 trillion as of 2021. The word "hedge", meaning a line of bushes around the perimeter of a field, has long been used as a metaphor for placing limits on risk. Early hedge funds sought to hedge specific investments against general market fluctuations by shorting other, similar assets. Nowadays, however, many different investment strategies are used, many of which do not "hedge" risk. During

From the eighteenth century onwards, this was a recognized category of mathematical activity, sometimes characterized as speculative mathematics , and at variance with the trend towards meeting the needs of navigation , astronomy , physics , economics , engineering , and other applications. Another insightful view put forth is that pure mathematics
3696-451: Is a mathematical science with specialized knowledge. The term "applied mathematics" also describes the professional specialty in which mathematicians work on problems, often concrete but sometimes abstract. As professionals focused on problem solving, applied mathematicians look into the formulation, study, and use of mathematical models in science , engineering , business , and other areas of mathematical practice. Pure mathematics
3808-464: Is a ruse and that the fund investors owe taxes at the higher rate. Because Medallion could claim that it owned just one asset – the option – and held it for more than a year, investors could declare their gains to be long-term investments. In September 2021, Simons, Mercer, and other Renaissance executives agreed to pay up to $ 7 billion in taxes and penalties to settle the dispute with the IRS. The settlement
3920-602: Is carried out by investment managers who identify and select investments, whereas systematic trading is based on mathematical models and executed by software with limited human involvement beyond the programming and updating of the software. These strategies can also be divided into trend or counter-trend approaches depending on whether the fund attempts to profit from following market trend (long or short-term) or attempts to anticipate and profit from reversals in trends. Within global macro strategies, there are further sub-strategies including "systematic diversified", in which
4032-666: Is common for hedge fund investment strategies to aim to achieve a positive return on investment regardless of whether markets are rising or falling (" absolute return "). Hedge funds can be considered risky investments; the expected returns of some hedge fund strategies are less volatile than those of retail funds with high exposure to stock markets because of the use of hedging techniques. Research in 2015 showed that hedge fund activism can have significant real effects on target firms, including improvements in productivity and efficient reallocation of corporate assets. Moreover, these interventions often lead to increased labor productivity, although
4144-833: Is considered to be one of the most successful hedge funds ever. From 1994 through mid-2014, it averaged a 71.8% annual return, before fees. The fund has been closed to outside investors since 1993 and is available only to current and past employees and their families. The firm bought out the last investor in the Medallion fund in 2005 and the investor community has not seen its returns since then. About 100 of Renaissance's some 275 employees are "qualified purchasers", meaning they generally have at least $ 5 million in assets to invest. The remaining are "accredited investors", generally worth at least $ 1 million. "Since 1988, his flagship Medallion fund has generated average annual returns of 66% before charging hefty investor fees—39% after fees—racking up trading gains of more than $ 100 billion. No one in

He worked with Sandor Straus, Jim Simons and another consultant, Henry Laufer , to overhaul Medallion's trading system over the course of six months. In 1990, Berlekamp led Medallion to a 55.9% gain, net of fees, and then returned to his duties as a Berkeley professor after selling out to Simons at six times the price for which he had bought his Axcom interests sixteen months earlier. Straus then took Berlekamp's place, running Medallion's revamped trading system, which returned 39.4% in 1991, 34% in 1992 and 39.1% in 1993, according to Medallion annual reports. The Medallion fund

Staff attribute the breadth of data on events peripheral to financial and economic phenomena that Renaissance takes into account, and the firm's ability to manipulate large amounts of data by deploying scalable technological architectures for computation and execution. Renaissance Technologies' hedge fund has employed mathematical models to analyze and execute trades, many of them automated. The firm uses computer-based models to predict price changes in easily traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions. Some also attribute

The number of known mathematicians grew when Pythagoras of Samos ( c. 582 – c. 507 BC ) established
7280-609: The effect of market swings whereas directional funds utilize trends and inconsistencies in the market and have greater exposure to the market's fluctuations. Hedge funds using a global macro investing strategy take large positions in share, bond, or currency markets in anticipation of global macroeconomic events in order to generate a risk-adjusted return . Global macro fund managers use macroeconomic ("big picture") analysis based on global market events and trends to identify opportunities for investment that would profit from anticipated price movements. While global macro strategies have
7392-431: The fee is to discourage short-term investing, reduce turnover, and deter withdrawals after periods of poor performance. Unlike management fees and performance fees, redemption fees are usually kept by the fund and redistributed to all investors. Hedge fund management firms are often owned by their portfolio managers , who are therefore entitled to any profits that the business makes. As management fees are intended to cover
7504-540: The firm's operating costs, performance fees (and any excess management fees) are generally distributed to the firm's owners as profits. Funds do not tend to report compensation, and so published lists of the amounts earned by top managers tend to be estimates based on factors such as the fees charged by their funds and the capital they are thought to have invested in them. Many managers have accumulated large stakes in their own funds and so top hedge fund managers can earn extraordinary amounts of money, perhaps up to $ 4 billion in

However, the financial crisis of 2007–2008 caused many hedge funds to restrict investor withdrawals and their popularity and AUM totals declined. AUM totals rebounded and in April 2011 were estimated at almost $ 2 trillion. As of February 2011 , 61% of worldwide investment in hedge funds came from institutional sources. In June 2011,

Prominent prizes in mathematics include the Abel Prize , the Chern Medal , the Fields Medal , the Gauss Prize , the Nemmers Prize , the Balzan Prize , the Crafoord Prize , the Shaw Prize , the Steele Prize , the Wolf Prize ,
8288-585: The four main categories, there are several strategies that do not entirely fit into these categories. For an investor who already holds large quantities of equities and bonds, investment in hedge funds may provide diversification and reduce the overall portfolio risk. Managers of hedge funds often aim to produce returns that are relatively uncorrelated with market indices and are consistent with investors' desired level of risk. While hedging can reduce some risks of an investment it usually increases others, such as operational risk and model risk , so overall risk
8400-652: The fund and investors. According to the Financial Times , "big hedge funds have some of the most sophisticated and exacting risk management practices anywhere in asset management." Hedge fund managers that hold a large number of investment positions for short periods are likely to have a particularly comprehensive risk management system in place, and it has become usual for funds to have independent risk officers who assess and manage risks but are not otherwise involved in trading. A variety of different measurement techniques and models are used to estimate risk according to
8512-654: The fund trades in diversified markets, or sector specialists such as "systematic currency", in which the fund trades in foreign exchange markets or any other sector specialisation. Other sub-strategies include those employed by commodity trading advisors (CTAs), where the fund trades in futures (or options ) in commodity markets or in swaps. This is also known as a "managed future fund". CTAs trade in commodities (such as gold) and financial instruments, including stock indices . They also take both long and short positions, allowing them to make profit in both market upswings and downswings. Most global macro managers tends to be
8624-436: The fund's net asset value , whereas private-equity funds generally invest in illiquid assets and return capital only after a number of years. Other than a fund's regulatory status, there are no formal or fixed definitions of fund types, and so there are different views of what can constitute a "hedge fund". Although hedge funds are not subject to the many restrictions applicable to regulated funds, regulations were passed in
8736-464: The fund's leverage, liquidity, and investment strategy. Non-normality of returns, volatility clustering and trends are not always accounted for by conventional risk measurement methodologies and so in addition to value at risk and similar measurements, funds may use integrated measures such as drawdowns . In addition to assessing the market-related risks that may arise from an investment, investors commonly employ operational due diligence to assess
8848-582: The fund. On 25 September 2008, Renaissance wrote a comment letter to the Securities and Exchange Commission , discouraging them from implementing a rule change that would have permitted the public to access information regarding institutional investors' short positions, as they can currently do with long positions. The company cited a number of reasons for this, including the fact that "institutional investors may alter their trading activity to avoid public disclosure". In July 2014, Renaissance Technologies
8960-724: The fund’s worst year was a 21 percent gain, after subtracting fees. Medallion reaped a 98.2 percent gain in 2008, the year the Standard & Poor’s 500 Index lost 38.5 percent." In 1988, Renaissance established its most profitable fund, the Medallion fund (previously the Limroy Colombian fund), which used an expanded form of Leonard Baum 's mathematical models improved by algebraist James Ax to explore correlations from which they could profit. Simons and Ax, who were classmates at UC Berkeley , started Medallion, which they named after their awards in mathematics. The initial success of
9072-418: The hedge fund management firms with the greatest AUM were Bridgewater Associates (US$ 58.9 billion), Man Group (US$ 39.2 billion), Paulson & Co. (US$ 35.1 billion), Brevan Howard (US$ 31 billion), and Och-Ziff (US$ 29.4 billion). Bridgewater Associates had $ 70 billion in assets under management as of March 2012 . At the end of that year, the 241 largest hedge fund firms in
9184-402: The hedge fund manager must identify an upcoming event that will increase or decrease the value of the company's equity and equity-related instruments. Other event-driven strategies include credit arbitrage strategies, which focus on corporate fixed income securities; an activist strategy, where the fund takes large positions in companies and uses the ownership to participate in the management;
9296-523: The idea of trading with mathematical models and took to fundamental trading, Simons brought in algebraist James Ax from Cornell University. Ax expanded Baum's models for trading currencies to cover any commodity future and subsequently Simons set up Ax with his own trading account, Axcom Ltd., which eventually gave birth to the profitable fund — Medallion. During the 1980s, Ax and his researchers improved on Baum's models and used them to explore correlations from which they could profit. "From 2001 through 2013,
9408-633: The imposing problems presented in related scientific fields. With professional focus on a wide variety of problems, theoretical systems, and localized constructs, applied mathematicians work regularly in the study and formulation of mathematical models . Mathematicians and applied mathematicians are considered to be two of the STEM (science, technology, engineering, and mathematics) careers. The discipline of applied mathematics concerns itself with mathematical methods that are typically used in science, engineering, business, and industry; thus, "applied mathematics"
9520-509: The investment world comes close. Warren Buffett, George Soros, Peter Lynch, Steve Cohen, and Ray Dalio all fall short." By 2000, the computer-driven Medallion fund had an average annual return of 34% after fees from its 1988 inception. Simons ran Renaissance until his retirement in late 2009. Between January 1993 and April 2005, Medallion only had 17 losing months and out of 49 quarters over the same period, Medallion had only three losing quarters. Between 1989-2005 Medallion had only one year showing
9632-580: The kind of research done by private and individual scholars in Great Britain and France. In fact, Rüegg asserts that the German system is responsible for the development of the modern research university because it focused on the idea of "freedom of scientific research, teaching and study." Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education , and then proceed to specialize in topics of their own choice at
9744-474: The king of Prussia , Fredrick William III , to build a university in Berlin based on Friedrich Schleiermacher 's liberal ideas; the goal was to demonstrate the process of the discovery of knowledge and to teach students to "take account of fundamental laws of science in all their thinking." Thus, seminars and laboratories started to evolve. British universities of this period adopted some approaches familiar to
9856-539: The management fee from larger funds can generate a significant part of a manager's profits, and as a result some fees have been criticized by some public pension funds, such as CalPERS , for being too high. The performance fee is typically 20% of the fund's profits during any year, though performance fees range between 10% and 50%. Performance fees are intended to provide an incentive for a manager to generate profits. Performance fees have been criticized by Warren Buffett , who believes that because hedge funds share only
9968-456: The market overall. Hedge fund managers can use various types of analysis to identify price discrepancies in securities, including mathematical, technical , or fundamental techniques. Relative value is often used as a synonym for market neutral , as strategies in this category typically have very little or no directional market exposure to the market as a whole. Other relative value sub-strategies include: In addition to those strategies within
10080-592: The market, the particular instrument use, the market sector the fund specializes in ( e.g. , healthcare), the method used to select investments, and the amount of diversification within the fund. There are a variety of market approaches to different asset classes , including equity , fixed income , commodity , and currency . Instruments used include equities, fixed income, futures , options , and swaps . Strategies can be divided into those in which investments can be selected by managers, known as "discretionary/qualitative", or those in which investments are selected using
10192-403: The matter. The $ 75 billion firm’s market-neutral fund dropped about 27% and its global-equities fund lost about 25%... The firm, founded by former codebreaker Jim Simons, told investors that its losses are due to being under-hedged during March’s collapse and then over-hedged in the rebound from April through June. That happened because models that had “overcompensated” for the original trouble. “It
10304-413: The one-year Treasury bill rate plus a spread. A "soft" hurdle means the performance fee is calculated on all the fund's returns if the hurdle rate is cleared. A "hard" hurdle is calculated only on returns above the hurdle rate. By example the manager sets a hurdle rate equal to 5%, and the fund return 15%, incentive fees would only apply to the 10% above the hurdle rate. A hurdle is intended to ensure that
10416-499: The opportunity for larger gains is weighed against the possibility of greater losses. Hedge funds employing leverage are likely to engage in extensive risk management practices. In comparison with investment banks , hedge fund leverage is relatively low; according to a National Bureau of Economic Research working paper, the average leverage for investment banks is 14.2, compared to between 1.5 and 2.5 for hedge funds. Some types of funds, including hedge funds, are perceived as having
10528-481: The possibility that the merger or acquisition will not go ahead as planned; hedge fund managers will use research and analysis to determine if the event will take place. Special situations are events that impact the value of a company's stock, including the restructuring of a company or corporate transactions including spin-offs , share buy backs , security issuance/repurchase, asset sales, or other catalyst-oriented situations. To take advantage of special situations
10640-531: The probability and likely cost of the occurrence of an event such as death, sickness, injury, disability, or loss of property. Actuaries also address financial questions, including those involving the level of pension contributions required to produce a certain retirement income and the way in which a company should invest resources to maximize its return on investments in light of potential risk. Using their broad knowledge, actuaries help design and price insurance policies, pension plans, and other financial strategies in
10752-491: The profits and not the losses, such fees create an incentive for high-risk investment management. Performance fee rates have fallen since the start of the credit crunch . Almost all hedge fund performance fees include a " high water mark " (or "loss carryforward provision"), which means that the performance fee only applies to net profits ( i.e. , profits after losses in previous years have been recovered). This prevents managers from receiving fees for volatile performance, though
10864-484: The real world, many applied mathematicians draw on tools and techniques that are often considered to be "pure" mathematics. On the other hand, many pure mathematicians draw on natural and social phenomena as inspiration for their abstract research. Many professional mathematicians also engage in the teaching of mathematics. Duties may include: Many careers in mathematics outside of universities involve consulting. For instance, actuaries assemble and analyze data to estimate
10976-416: The risk that error or fraud at a hedge fund might result in a loss to the investor. Considerations will include the organization and management of operations at the hedge fund manager, whether the investment strategy is likely to be sustainable, and the fund's ability to develop as a company. Since hedge funds are private entities and have few public disclosure requirements, this is sometimes perceived as
11088-454: The same types of risk as other investment classes, including liquidity risk and manager risk. Liquidity refers to the degree to which an asset can be bought and sold or converted to cash; similar to private-equity funds, hedge funds employ a lock-up period during which an investor cannot remove money. Manager risk refers to those risks which arise from the management of funds. As well as specific risks such as style drift , which refers to
11200-403: The seventeenth century at Oxford with the scientists Robert Hooke and Robert Boyle , and at Cambridge where Isaac Newton was Lucasian Professor of Mathematics & Physics . Moving into the 19th century, the objective of universities all across Europe evolved from teaching the "regurgitation of knowledge" to "encourag[ing] productive thinking." In 1810, Alexander von Humboldt convinced
11312-762: The success of Renaissance in general and Medallion in particular, Simons has been described as the "best money manager on earth". Simons ran Renaissance until his retirement in late 2009. He continued to play a role at the firm as non-executive chairman, which he stepped down from in 2021, and remained invested in its funds, particularly the Medallion fund until his death in 2024. The company is now run by Peter Brown (after Robert Mercer resigned). Both of them were computer scientists specializing in computational linguistics who joined Renaissance in 1993 from IBM Research . The fund has $ 165 billion in discretionary assets under management (including leverage) as of April 2021. James Simons founded Renaissance Technologies following

An event-driven investment strategy finds investment opportunities in corporate transactional events such as consolidations, acquisitions , recapitalizations , bankruptcies , and liquidations . Managers employing such a strategy capitalize on valuation inconsistencies in the market before or after such events, and take
11648-743: The use of leverage and derivative instruments . In the United States, financial regulations require that hedge funds be marketed only to institutional investors and high-net-worth individuals . Hedge funds are considered alternative investments . Their ability to use leverage and more complex investment techniques distinguishes them from regulated investment funds available to the retail market, commonly known as mutual funds and ETFs . They are also considered distinct from private equity funds and other similar closed-end funds as hedge funds generally invest in relatively liquid assets and are usually open-ended . This means they typically allow investors to invest and withdraw capital periodically based on

RIEF once again struggled in the high volatility environment of 2020. According to an article in Bloomberg in November 2020, Renaissance saw a decline of about 20% through October in its long-biased fund, according to a person familiar with
11872-943: Was Al-Khawarizmi . A notable feature of many scholars working under Muslim rule in medieval times is that they were often polymaths. Examples include the work on optics , maths and astronomy of Ibn al-Haytham . The Renaissance brought an increased emphasis on mathematics and science to Europe. During this period of transition from a mainly feudal and ecclesiastical culture to a predominantly secular one, many notable mathematicians had other occupations: Luca Pacioli (founder of accounting ); Niccolò Fontana Tartaglia (notable engineer and bookkeeper); Gerolamo Cardano (earliest founder of probability and binomial expansion); Robert Recorde (physician) and François Viète (lawyer). As time passed, many mathematicians gravitated towards universities. An emphasis on free thinking and experimentation had begun in Britain's oldest universities beginning in
11984-500: Was also questioned by the Internal Revenue Service (IRS). The higher rates for the five years under investigation would have been 44.4 percent, as compared to 35 percent, whereas the lower rate was 15 percent, as compared to 23.8 percent. The IRS contend[ed] that the arrangement Renaissance’s Medallion fund had with the banks, in which the fund owned option contracts rather than the underlying financial instruments,
12096-422: Was among the largest in history. According to OpenSecrets , Renaissance was the top financial firm contributing to federal campaigns in the 2016 election cycle, donating $ 33,108,000 by July. By comparison, over that same period sixth ranked Soros Fund Management has contributed $ 13,238,551. Renaissance's managers were also active in the 2016 cycle, contributing nearly $ 30 million by June, with Mercer ranking as

Renaissance Institutional Equities Fund had difficulty with the higher volatility environment that persisted throughout the end of the summer of 2007. According to an article in Bloomberg in August 2007, "James Simons's $ 29 billion Renaissance Institutional Equities Fund fell 8.7% in August 2007 when his computer models used to buy and sell stocks were overwhelmed by securities' price swings. The two-year-old quantitative, or 'quant', hedge fund now has declined 7.4 percent for

The focus of the tax avoidance investigation was Renaissance's trading strategy — which involved transactions with banks such as Barclays Plc and Deutsche Bank AG — through which profits converted from rapid trading were converted into lower-taxed, long-term capital gains. The strategy
